In vitro evaluation of surface based non-invasive breast cancer screening with Digital Image based Elasto Tomography (DIET)

Abstract: Digital Image-based Elasto Tomography (DIET) is a non-invasive breast cancer screening modality that induces vibrations into a breast and images its surface motion with digital cameras. Disturbances in the motion are caused by areas of higher stiffness within the breast, potentially cancerous tumors. A concept is presented to detect the angular location of a tumor by analyzing the phase delay of the vibrations on the surface. The approach is verified experimentally on silicone phantom breasts with stiffer incl… Show more

“…The markers purpose of applying these markers was to ensure robust motion tracking when optically imaged with the DIET system. 28,29,32,33,47,48,[62][63][64] During the imaging procedure each one of 250 these 13 phantoms, was individually mounted on a metallic plate (200 mm x 150 mm) and hung pendant through a hole in the DIET clinical prototype. The phantom was vibrated using harmonic sinusoidal actuation of 0.5 mm amplitude, over a range of 10-50 Hz at a step size of 1 Hz.…”

“…Motion is reconstructed in 3D to obtain Bode plots and analyze effects of stiffer inclusions on the amplitude of motion, phase disruption and variation in natural frequencies. 28,29,44,[47][48][49][50] The phantoms required for in vitro DIET trials, need to mimic an average female breast, both geometrically as well as from stiffness point of 105…”

“…Alternatively, the surface motion can be used directly to estimate the presence of a tumor. 4 To estimate the surface motion and reconstruct the breast shape, five calibrated cameras are positioned around the breast. The image processing then consists of two steps: tracking and correspondence estimation.…”
